通过单网格相衬成像从单个X射线投影进行材料分解
Material decomposition from a single x-ray projection via single-grid phase contrast imaging
摘要：
这项研究描述了一种新的方法，材料分解X射线成像，利用相位对比度，以增加灵敏度弱衰减样品，并作为一个补充测量衰减，因此允许两个重叠的材料被分离。使用单次曝光，单网格X射线相位衬度成像技术，与一种新的校正，旨在消除传播为基础的相位效应，在衰减图像中的锐边捕获的测量。单次曝光技术的使用意味着可以以高速序列收集图像。显示了已知双材料样品和生物样本的结果。
英文摘要：
This study describes a new approach for material decomposition in x-ray imaging, utilising phase contrast to both increase sensitivity to weakly-attenuating samples and to act as a complementary measurement to attenuation, therefore allowing two overlaid materials to be separated. The measurements are captured using the single-exposure, single-grid x-ray phase contrast imaging technique, with a novel correction that aims to remove propagation-based phase effects seen at sharp edges in the attenuation image. The use of a single-exposure technique means that images could be collected in a high-speed sequence. Results are shown for both a known two-material sample and for a biological specimen.
